Alkaloidal components in the poisonous plant, Ipomoea carnea (Convolvulaceae).
Natural intoxication of livestock by the ingestion of Ipomoea carnea (Convolvulaceae) sometimes occurs in tropical regions of the world. Polyhydroxylated alkaloids were isolated from the leaves, flowers, and seeds of the poisonous plant and characterized. Chromatographic separation of the leaf extract resulted in the isolation of swainsonine (1), 2-epi-lentiginosine (2), calystegines B(1) (3), ...
متن کاملNew species of Ipomoea (Convolvulaceae) from South America
The importance of discovering, describing and cataloguing poorly known species in herbarium collections is discussed. It is a spur to efforts at rediscovery and consequent conservation efforts. The problems faced in describing species from limited material are discussed and our methods and criteria in making a decision are described. Prospects for future novelties are briefly assessed. Fifteen ...
متن کاملPoisoning of 'binthamburu' (Ipomoea asarifolia) due to misidentification as 'kankun' (Ipomoea aquatica).
Ingestion of 'Binthamburu' (Ipomoea asarifolia) by misidentification as 'kankun' (Ipomoea aquatica) as a leafy vegetable causes acute gastrointestinal symptoms and confusion. The authors have encountered four such cases in the past. All cases have been recorded from the dry zone of the country. Both plants are two trailing vines similar in their appearance and preferring the wet habitats. Durin...
متن کاملSystematics of Ipomoea subgenus Quamoclit (Convolvulaceae) based on ITS sequence data and a Bayesian phylogenetic analysis.
A Bayesian phylogenetic analysis of 36 Ipomoea species using sequence data from the internal transcribed spacer region was compared with classification schemes based on traditional methods and a previously published cpDNA restriction fragment length polymorphism (RFLP) study. These molecular studies support a diversity of groups that were circumscribed on the basis of phenetic principles and ag...
متن کاملInbreeding depression and selfing rate of Ipomoea hederacea var. integriuscula (Convolvulaceae).
Inbreeding depression and selfing rate were investigated in the self-compatible vine Ipomoea hederacea to assess the variability of the breeding system. Inbreeding depression differed between populations and the magnitude varied at germination, growth (as measured by aboveground biomass), and reproductive potential. Plants from Macon County, Alabama, USA, had significant inbreeding depression (...
